General description

1,3,5-Trimethoxybenzene effectively cleaves p-methoxybenzyl protecting group on various alcohols and acids. It is the major scent compound present in Chinese rose species.

Application

1,3,5-Trimethoxybenzene was used to study the photodeoxygenation of 1,2-benzodiphenylene sulfoxide. It was employed as secondary standard in quantitative proton NMR spectroscopy of pharmaceuticals.

One-electron oxidation of alcohols such as methanol, ethanol, and 2-propanol by 1,3,5-trimethoxybenzene radical cation (TMB*+) in the excited state (TMB*+*) was observed during the two-color two-laser flash photolysis. TMB*+ was formed by the photoinduced bimolecular electron-transfer reaction from TMB to

1,3,5-Trimethoxybenzene is a key component of the Chinese rose odor. This compound is synthesized in three successive methylation steps from phloroglucinol, the initial precursor. A novel, to our knowledge, phloroglucinol O-methyltransferase (POMT) characterized here methylates the first step to produce
